The Custom Programmable Delay Line (CPDL-100A) offers custom programmable delay at customer specified delay step and total delay range limits. The CPDL-100A does not use the Electro-Mechanical Trombone delay line structure, but is made entirely from precision cut phase-matched semi-rigid coaxial microwave cables and coaxial relays. The CPDL-100A is an excellent fit in signal applications where resolution to 10 ps step size or larger is adequate or where extended total delay up to 200 ns is required.
